Answer: 4/5
Step-by-step explanation:
1. split each candy bar into fifths
2. 20 pieces total
3. 20 ÷ 5 = 4
4. So each person gets 4 pieces (4/5)
Answer:
log (16)=2 in base 3x-5
==>16=2^(3x-5)
==>2^4=2^(3x-5)
==>4=3x-5
==>3x=9
==>x=3
Step-by-step explanation:
Answer: 0.628
Step-by-step explanation:
Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702
Sample size : n= 54
Mean :
Standard deviation:
The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :
Hence, the required probability = 0.628

Answer:
The area of rhombus = 24
Step-by-step explanation:
The area of rhombus = base times height
For the given rhombus :
Height = The length of DP
Base = the length of any side of the rhombus as AB
The length ot two point (x₁ , y₁) and (x₂ , y₂) =
From the given figure:
D = (-5,-2) , P = (-3.8 , 1.6) , A = (1,0) , B = (7 , -2)
DP = = √14.4
AB = = √40
So,
<u>The area of rhombus = √14.4 * √40 = √576 = 24</u>
